Syntax
IFERROR(value, [value_if_error])
value – The value to return if value itself is not an error.
value_if_error – [ OPTIONAL – blank by default ] – The value the function returns if value is an error.
Notes
IFERROR(exp1,exp2) is logically equivalent to IF(NOT(ISERROR(exp1)),exp1,exp2). Ensure that this is the desired behavior.
